They took more than 300 different measurements of the actor and comedian at a Los Angeles studio to make sure the model is as life-like as possible before it is unveiled at Madame Tussauds in central London.

The Get Him To The Greek star, who is engaged to American singer Katy Perry, said: "Now that I'm monogamous I want to live vicariously through wax Russell, I insist that he's placed next to wax Helen Mirren and I hope they melt into one sexy blob."

The wax model will be dressed in a trademark Brand outfit complete with make-up, skin-tight trousers and jewellery.

Russell is currently filming a remake of the Dudley Moore film Arthur in the US, in which he plays the title role.
